Overview
The Bosch RH328VC is a corded electric drill running on 120 volts and drawing 8 amps, spinning at 900 RPM. It weighs 3.82 pounds and ships in a case measuring 19 by 14 by 5 inches.
An 8 amp motor is a strong draw for a drill this light, which points to a tool built for sustained, demanding drilling rather than light household use. The 900 RPM speed is on the slower end, which typically favors torque over quick hole boring.
- 8 amp corded motor
- 120 volt power
- 900 RPM speed
- 3.82 pound weight
Who it's for
Suits users drilling into tougher material who want a corded tool with dependable power and no battery to manage. Casual users doing occasional light drilling may find it more tool than they need.
Pros and cons
- 8 amp motor gives strong sustained power
- Corded design means no battery to charge or replace
- Under 4 pounds despite the powerful motor
- 900 RPM is slower, so quick holes take longer
- Corded operation limits use away from an outlet
Performance notes
The 8 amp, 120 volt motor supplies steady power as long as it stays plugged in, avoiding the runtime limits of a battery tool. At 900 RPM the drill trades top end speed for torque, which suits harder drilling tasks over quick, light holes.
